The present disclosure provides carboxamides and sulfonamides as SMYD protein inhibitors, such as SMYD3 and SMYD2 inhibitors, and therapeutic methods of treating conditions and diseases wherein inhibition of SMYD proteins such as SMYD3 and SMYD2 provides a benefit.

BACKGROUND

Epigenetic regulation of gene expression is an important biological determinant of protein production and cellular differentiation and plays a significant pathogenic role in a number of human diseases. Epigenetic regulation involves heritable modification of genetic material without changing its nucleotide sequence. Typically, epigenetic regulation is mediated by selective and reversible modification (e.g., methylation) of DNA and proteins (e.g., histones) that control the conformational transition between transcriptionally active and inactive states of chromatin. These covalent modifications can be controlled by enzymes such as methyltransferases (e.g., SMYD proteins such as SMYD3 and SMYD2), many of which are associated with genetic alterations that can cause human disease, such as proliferative disorders. Thus, there is a need for the development of small molecules that are capable of inhibiting the activity of SMYD proteins such as SMYD3 and SMYD2.

The present disclosure encompasses the preparation and use of solvates of Compounds of the Disclosure. Solvates typically do not significantly alter the physiological activity or toxicity of the compounds, and as such may function as pharmacological equivalents. The term “solvate” as used herein is a combination, physical association and/or salvation of a compound of the present disclosure with a solvent molecule such as, e.g. a disolvate, monosulfate or hemisolvate, where the ratio of solvent molecule to compound of the present disclosure is about 2:1, about 1:1 or about 1:2, respectively. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding, in certain instances, the solvate can be isolated, such as when one or more solvent molecules are incorporated into the crystal lattice of a crystalline solid. Thus, “solvate” encompasses both solution-phase and isolatable solvates. Compounds of the Disclosure can be present as solvated forms with a pharmaceutically acceptable solvent, such as water, methanol, ethanol, and the like, and it is intended that the disclosure includes both solvated and unsolvated forms of Compounds of the Disclosure. One type of solvate is a hydrate. A “hydrate” relates to a particular subgroup of solvates where the solvent molecule is water. Solvates typically can function as pharmacological equivalents. Preparation of solvates is known in the art. See, for example, M. Cairn et al, J. Pharmaceut. Sci., 93(3):601-611 (2004), which describes the preparation of solvates of fluconazole with ethyl acetate and with water. Similar preparation of solvates, hemisolvates, hydrates, and the like are described by E. C. van Tender et al., AAPS Pharm. Sci. Tech., 5(1):Article 12 (2004), and A. I. Bingham et al., Chem. Commun. 603-604 (2001), A typical, non-limiting, process of preparing a solvate would involve dissolving a Compound of the Disclosure in a desired solvent (organic, water, or a mixture thereof) at temperatures above 20° C. to about 25° C., then cooling the solution at a rate sufficient to form crystals, and isolating the crystals by known methods, e.g., filtration. Analytical techniques such as infrared spectroscopy can be used to confirm the presence of the solvent in a crystal of the solvate.

Since Compounds of the Disclosure are inhibitors of SMYD proteins, such as SMYD3 and SMYD2, a number of diseases, conditions, or disorders mediated by SMYD proteins, such as SMYD3 and SMYD2, can be treated by employing these compounds.

The term “insert” means information accompanying a pharmaceutical product that provides a description of how to administer the product, along with the safety and efficacy data required to allow the physician, pharmacist, and patient to make an informed decision regarding use of the product. The package insert generally is regarded as the “label” for a pharmaceutical product.

The term “disease” or “condition” or “disorder” denotes disturbances and/or anomalies that as a rule are regarded as being pathological conditions or functions, and that can manifest themselves in the form of particular signs, symptoms, and/or malfunctions. As demonstrated below, Compounds of the Disclosure inhibit SMYD proteins, such as SMYD3 and SMYD2 and can be used in treating diseases and conditions such as proliferative diseases, wherein inhibition of SMYD proteins, such as SMYD3 and SMYD2 provides a benefit.

In some embodiments, the Compounds of the Disclosure can be used to treat a “SMYD protein mediated disorder” (e.g., a SMYD3-mediated disorder or a SMYD2-mediated disorder). A SMYD protein mediated disorder is any pathological condition in which a SMYD protein is know to play a role. In some embodiments, a SMYD-mediated disorder is a proliferative disease.

In some embodiments inhibiting SMYD proteins, such as SMYD3 and SMYD2, is the inhibition of the activity of one or more activities of SMYD proteins such as SMYD3 and SMYD2. In some embodiments, the activity of the SMYD proteins such as SMYD3 and SMYD2 is the ability of the SMYD protein such as SMYD3 or SMYD2 to transfer a methyl group to a target protein (e.g., histone). It should be appreciated that the activity of the one or more SMYD proteins such as SMYD3 and SMYD2 may be inhibited in vitro or in vivo. Exemplary levels of inhibition of the activity one or more SMYD proteins such as SMYD3 and SMYD2 include at least 10% inhibition, at least 20% inhibition, at least 30% inhibition, at least 40% inhibition, at least 50% inhibition, at least 60% inhibition, at least 70% inhibition, at least 10% inhibition, at least 90% inhibition, and up to 100% inhibition.

The SMYD (SET and MYND domain) family of lysine methyltransferases (KMTs) plays pivotal roles in various cellular processes, including gene expression regulation and DNA damage response. The family of human SMYD proteins consists of SMYD1, SMYD2; SMYD3, SMYD4 and SMYD5. SMYD1, SMYD2, and SMYD3 share a high degree of sequence homology and, with the exception of SMYD5, human SMYD proteins harbor at least one C-terminal tetratrico peptide repeat (TPR) domain. (See e.g., Abu-Farha et al. J. Mol Cell Biol. (2011) 3 (5) 301-308). The SMYD proteins have been found to be linked to various cancers (See e.g., Hamamoto et al, Nat Cell. Biol. 2004, 6: 731-740), Hu et al. Cancer Research 2009, 4067-4072, and Komatsu et al. Carcinogenesis 2009, 301139-1146.)

SMYD3 is a protein methyltransferase toured to be expressed at high levels in a number of different cancers (Hamamoto, R., et al., Nat. Cell Biol., 6(8):731-40 (2004)). SMYD3 likely plays a role in the regulation of gene transcription and signal transduction pathways critical for survival of breast, liver, prostate and lung cancer cell lines (Hamamoto, R., et al., Nat. Cell Biol., 6(8):731-40 (2004); Hamamoto, R., et al., Cancer Sci., 97(2):113-8 (2006); Van Alter, G. S., et al., Epigenetics, 7(4):340-3 (2012); Liu, C., et al., J. Natl. Cancer Inst., 105(22):1119-28 (2013); Mazur, P. K., et al., Nature, 510(7504):283 (2014)).

Genetic knockdown of SMYD3 leads to a decrease in proliferation of a variety of cancer cell lines (Hamamoto, R., et al., Nat. Cell Biol., 6(8):731-40 (2004); Hamamoto, R., et al., Cancer Sci., 97(2):113-8 (2006); Van Allen, G. S., et al., Epigenetics, 7(41:340-3 (2012); Liu, C., et al., J. Natl. Cancer Inst., 105(22):1719.28 (2013); Mazur, P. K., et al., Nature, 510(7504):283.7 (2014)). Several studies employing RNAi-based technologies have shown that ablation of SMYD3 in hepatocellular carcinoma cell lines greatly reduces cell viability and that its pro-survival role is dependent on its catalytic activity (Hamamoto, R., et al., Nat. Cell Biol., 6(8):731-40 (2004); Van Aller, G. S., et al., Epigenetics, 7(4):340-3 (2012)). Moreover, SMYD3 has also been shown to be a critical mediator of transformation resulting from gain of function mutations in the oncogene, KRAS for both pancreatic and lung adenocarcinoma in mouse models. The dependence of KRAS on SMYD3 was also shown to be dependent on its catalytic activity (Mazur, P. K., et al., Nature, 510(7504):283-7 (2014)). SMYD3 function has also been implicated in colorectal cancers and RNAi mediated knockdown of SMYD3 has been shown to impair colorectal cell proliferation, (Peserico et al., Cell Physiol. 2015 Feb. 28. doi: 10.1002/jcp.249; 5. [Epub ahead of print]).

Furthermore, SMYD3 function has also been shown to play a role in immunology and development. For instance, de Almeida reported that SMYD3 plays a role in generation of inducible regulatory T cells (iTreg) cells, in a mouse model of respiratory syncytial virus (RSV) infection, a model in which iTreg cells have a critical role in regulating lung pathogenesis, SMYD3−/− mice demonstrated exacerbation of RSV-induced disease related to enhanced proinflammatory responses and worsened pathogenesis within the lung (de Almeida et al. Mucoscal Immunol. 2015 Feb. 11. doi: 10.1038/mi.2015.4. [Epub ahead of print]). In addition, as to development, Proserpio et al. have shown the importance of SMYD3 in the regulation of skeletal muscle atrophy, (Proserpio et al, Genes Dev. 2013 Jun. 1; 27(11):1299-3121, while Fujii et al. have elucidated the role of SMYD3 in cardiac and skeletal muscle development (Fujii et al. PLoS One, 2011; 6(8):02349).

SMYD2 (SET and MYND domain-containing protein 2) was first characterized as protein that is a member of a sub-family of SET domain containing proteins which catalyze the site-specific transfer of methyl groups onto substrate proteins. SMYD2 was initially shown to have methyltransferase activity towards lysine 36 on historic H3 (H3K36) but has subsequently been shown to have both historic and non-histone methyltransferase activity.

SMYD2 has been implicated in the pathogenesis of multiple cancers. It has been shown to be over-expressed, compared to matched normal samples, in tumors of the breast, cervix, colon, kidney, liver, head and neck, skin, pancreas, ovary, esophagus and prostate, as well as hematologic malignancies such as AML, B- and T-ALL, CLL and MCL, suggesting a role for SMYD2 in the biology of these cancers. More specifically, studies using genetic knock-down of SMYD2 have demonstrated anti-proliferative effects in esophageal squamous cell carcinoma (ESCC), bladder carcinoma and cervical carcinoma cell lines. (See e.g., Komatsu et al., Carcinogenesis 2009, 30, 1139, and Cho et al., Neoplasia. 2012 June; 14(6):476-86). Moreover, high expression of SMYD2 has been shown to be a poor prognostic factor in both ESCC and pediatric ALL. (See e.g., Komatsu et al. Br J Cancer. 2015 Jan. 20; 112(2):357-64, and Sakamoto et al., Leuk Res. 2014 April; 38(4):496-502). Recently, Nguyen et al., have shoe that a small molecule inhibitor of SMYD2 (LLY-507) inhibited the proliferation of several esophageal, liver and breast cancer cell lines in a dose-dependent manner. (Nguyen et al. J Biol Chem. 2015 Mar. 30. pii: jbc.M114.626861. [Epub ahead of prat]).

SMYD2 has also been implicated in immunology. For instance, Xu et al. have shown that SMYD2 is a negative regulator of macrophage activation by suppressing Interleukin-6 and TNF-alpha production. (Xu et al., J Biol Chem. 2015 Feb. 27:290(9):5414-23).

Molecular Biology

Full-length human SMYD3 isoform 1 (BAB86333) was inserted into a modified pET21b plasmid containing a His6 tag and TEV and SUMO cleavage sites. Because two common variants of SMYD3 exist in the population, site directed mutagenesis was subsequently performed to change amino acid 13 from all asparagine to a lysine, resulting in plasmid pEPZ533. A lysine at position 13 conforms to the more commonly occurring sequence (NP_001161212).

Protein Expression

E. coli (BL21 codon plus RIL strain, Stratagene) were transformed with plasmid pEPZ553 by mixing competent cells and plasmid DNA and incubating on ice for 30 minutes followed by heat shock at 42° C. for 1 minute and cooling on ice for 2 minutes Transformed cells were grown and selected on LB agar with 100 μg/mL ampicillin and 17 μg/mL chloramphenicol at 37° C. overnight. A single clone was used to inoculate 200 mL of LB medium with 100 μg/mL ampicillin and 17 μg/mL chloramphenicol and incubated at 37° C. on an orbital shaker at 180 rpm. Once in log growth, the culture was diluted 1:100 into 2 L of LB medium and grown until OD₆₀₀ was about 0.3 after which the culture was incubated at 15° C. and 160 rpm. Once OD₆₀₀ reached about 0.4, IPTG was added to a final concentration of 0.1 mM and the cells were grown overnight at 15 GC and 160 rpm. Cells were harvested by centrifugation at 8000 rpm, for 4 minutes at 4° C. and stored at −80° C. for purification,

Protein Purification

Expressed full-length human His-lagged SMYD3 protein was purified from cell paste by Nickel affinity chromatography after equilibration of the resin with Buffer A (25 mM Tris, 200 mM NaCl, 5% glycerol, 5 mM β-mercaptoethanol, pH7.8). The column was washed with Buffer B (Buffer A plus 20 mM imidazole) and His-tagged SMYD3 was eluted with Buffer C (Buffer A plus 300 mM imidazole). The His tag, TEV and SUMO cleavage sites were removed generating native SMYD3 by addition of ULP1 protein at a ratio of 1:200 (ULP1:SMYD3). Imidazole was removed by dialysis overnight in Buffer A. The dialyzed solution was applied to a second Nickel column and the native SMYD3 protein was collected from the column flow-through. The flow-through was dialyzed in Buffer D (25 mM iris, 5% glycerol, 5 mM β-mercaptoethanol, 50 mM NaCl, pH7.8) and ULP1 was removed using a Q sepharose fast flow column. SMYD3 was eluted in Buffer A and further purified using an S200 size-exclusion column equilibrated with Buffer A. SMYD3 was concentrated to 2 mg/mL with a final purity of 89%.

General Procedure for SMYD3 Enzyme Assays on MEKK2 protein Substrate

The assays were all performed in a buffer consisting of 25 mM Tris-Cl pH 8.0, 1 mM TCEP, 0.005% BSG, and 0.005% Tween 20, prepared on the day of use. Compounds in 100% DMSO (ltd) were spotted into a 384-well white opaque OptiPlate using a Bravo automated liquid, handling platform outfitted with a 384-channel head (Agilent Technologies). DMSO (1 ul) was added to Columns 11, 12, 23, 24, rows A-H for the maximum signal control and 1 ul of SAH, a known product and inhibitor of SMYD3, was added to columns 11, 12, 23, 24, rows I-P far the minimum signal control. A cocktail (40 ul) containing the SMYD3 enzyme was added by Multidrop Combi (Thermo-Fisher). The compounds were allowed to incubate with SMYD3 for 30 min at room temperature, then a cocktail (10 ul) containing SAM and MEKK2 was added to initiate the reaction (final volume Slue. The final concentrations of the components were as follows: SMYD3 was 0.4 nM, ³H-SAM was 8 nM, MEKK2 was 12 nM, SAH in the minimum signal control wells was 1 mM, and the DMSO concentration was 2%. The assays were stopped by the addition of non-radiolabeled SAM (100) to a final concentration of 100 uM, which dilutes the ³H-SAM to a level where its incorporation into MEKK2 is no longer detectable. Radiolabeled MEKK2 was detected using a scintillation proximity assay (SPA). 10 uL of a 10 mg/mL solution of SPA beads in 0.5 M citric acid was added and the plates centrifuged at 600 rpm for 1 min to precipitate the radiolabeled MEKK2 onto the SPA beads. The plates were then read in a PerkinElmer TopCount plate reader to measure the quantity of ³H-labeled MEKK2 as disintegrations per minute (dpm) or alternatively, referred to as counts per minute (cpm).

Calculations:

First, the ratio for each well was determined by:

$\left( \frac{{Trimethyl}\mspace{14mu}{MEKK}\; 2\mspace{14mu} 800\mspace{14mu}{mn}\mspace{14mu}{value}}{{flag}\mspace{14mu}{tagged}\mspace{14mu}{MEKK}\; 2\mspace{14mu} 700\mspace{14mu}{mn}\mspace{14mu}{value}} \right)$

Each plate included fourteen control wells of DMSO only treatment (Minimum Inhibition) as well as fourteen control wells for maximum inhibition (Background). The average of the ratio values for each control type was calculated and used to determine the percent inhibition for each test well in the plate. Reference compound was serially diluted two-fold in MIND for a total of nine test concentrations, beginning at 40 μM. Percent inhibition was calculated (below).

${{Percent}\mspace{14mu}{Inhibition}} = {100 - \left( {\left( \frac{\left( {{Individual}\mspace{14mu}{Test}\mspace{14mu}{Sample}\mspace{14mu}{Ratio}} \right) - \mspace{45mu}\left( {{Background}\mspace{14mu}{Avg}\mspace{14mu}{Ratio}} \right)}{\left( {{Maximum}\mspace{14mu}{Inhibition}\mspace{14mu}{Ratio}} \right) - \mspace{11mu}\left( {{Background}\mspace{14mu}{Average}\mspace{14mu}{Ratio}} \right)} \right)*100} \right)}$

The assays were all performed in a buffer consisting of 20 mM Bicine (pH-7.6), 1 mM TCEP, 0.005% Bovine Skin Gelatin, and 0.002% Tween20, prepared on the day of use. Compounds in 100% DMSO (1 ul) were spotted into a polypropylene 384-well V-bottom plates (Greiner) using a Platemate Plus outfitted with a 384-channel head (Thermo Scientific). DMSO (1 ul) was added to Columns 11, 12, 23, 24, rows A-H for the maximum signal control and 1 ul of SAH, a known product and inhibitor of SMTYD2, was added to columns 11, 12, 23, 24, rows I-P for the minimum signal control. A cocktail (40 ul) containing the SMYD2 enzyme was added by Multidrop Combi (Thermo-Fisher). The compounds were allowed to incubate with SMYD2 for 30 ruin at room temperature, then a cocktail (10 ul) containing, ³H-SAM and peptide was added to initiate the reaction (final volume=51 ul). The final concentrations of the components were as follows: SMYD2 was 1.5 nM, ³H-SAM was 10 nM, and peptide was 60 nM, SAH in the minimum signal control wells was 1000 uM, and the DMSO concentration was 2%. The assays were stopped by the addition of non-radioactive SAM (10 ul) to a final concentration of 600 uM, which dilutes the ³H-SAM to a level where its incorporation into the peptide substrate is no longer detectable. 50 ul of the reaction in the 384-well polypropylene plate was then transferred to a 384-well Flashplate and the biotinylated peptides were allowed to bind to the streptavidin surface for at least 1 hour before being washed three times with 0.1% Tween20 in a Biotek ELx405 plate washer. The plates were then read in a PerkinElmer TopCount plate reader to measure the quantity of ³H-labeled peptide bound to the Flashplate surface, measured as disintegrations per minute (dpm) or alternatively, referred to as counts per minute (cpm).

%  inhibition  calculation ${\%\mspace{14mu}{inh}} = {100 - {\left( \frac{{dpm}_{cmpd} - {dpm}_{\min}}{{dpm}_{\max} - {dpm}_{\min}} \right) \times 100}}$

Where dpm=disintegrations per minute, cmpd=signal in assay well, and min and max are the respective minimum and maximum signal controls.

Four-parameter  IC50  fit ${\%\mspace{14mu}{inhibition}} = {{Bottom} + \frac{\left( {{Top} - {Bottom}} \right)}{\left( {1 + \left( {{IC}_{50}/\lbrack I\rbrack} \right)^{{Hill}\mspace{11mu}{Coefficient}}} \right)}}$

Where top and bottom are the normally allowed to float, but may be fixed at 100 or 0 respectively in a 3-parameter fit. The Hill Coefficient normally allowed to float but may also be fixed at 1 in a 3-parameter fit. I is the compound concentration.
